GUMMING MACHINE.

Application filed August 12, 1921. Serial No. 491,757.

To all whom it may concern:

Be it known that I, Anon-aw BROWN Mo- Lainama subjectof the King ofGreat Brit .ain, residing at the city of Toronto, in the 5 county ofYorkand Province. of Ontario.

Dominion of Canada, have invented new and useful Improvements in GummingMachines, of which the following is a specification. 1 y

My invention relates to agumming machine in which liquid glue or otherpaste is distributed by a roller suitably j ournaled in th machine, incombination with the necessary operating mechanism, and arranged in 1longitudinal. relation with a reservoir or trough suitably support-edand adapted to vbe actuated by foot or hand power, to regulate andsupply the liquid glue or paste to the periphery of the roller as itturns either continuously or intermittently accordingly with the classor amount of work passing through the machine and at the discretion ofthe operator.

I make no especial claim to the operating mechanism, otherthan thecombination and functional features of the reservoir or glue trough,which is the main object of my invention, the essential object being toprovide against churning, foaming and the overflow of the glue caused byagitation resulting from the turning of the distributing roller, whichcloses one side of the reservoir, and to prevent any agitation thedistributing roller is separated from the main volume of the,

glue by an adjusting and regulating gate positioned in the reservoir inclose proximity and in parallel relation with the periphery of theroller.

In the accompanying drawings 40 Figure 1 is a sectional elevational viewof the machine; and

Figure 2 is a detail sectionalyicw of the reservoir.

a designates one side of the main frame of the machine, in which thevarious operating parts are suitably journaled and set.

59 I make no claim to the shape or nature of the frame, as my device isespecially adapted to be used in connection with any of the variousclasses of gumming machines.

I) is a gum distributing roller which is suitably journaled crosswise inthe main frame of the machine, and 0 is a canvas carrier on whichtheglued materials are carried away from the distributing roller 6. Thecanvas carrier 0 consists of an endless canvas belt passing overrollers, one of the rollers oZ being journaled in the main frame a inparallel and close proximity with the distributing roller 1), the otherroller (not shown) is supported and journaled in a frame situated atsome distance from the machine.

e and f designate a pair of rollers suitably journaled in the main frameof'the machine slightly forward and in parallel relation with thedistributing roller 6, at the inner end of the work table g, supportedon the front end of the main frame, and from which thematerial to begummed is passed to the guide rollers e and f, to be directed to theperiphery of the distributing roller 6, and by which the gum is equallydistributed, and carried to engage with a series of picker fingers it,aivotally carried on a rod 6 extending across the machine.

The gummed material adhering to the periphery of the distributing roller6 as the roller turns, carries it until it contacts with the fingers It,by which. it is picked off and caused to depositon the canvas carrier,and conveyed to where th operatorsmay remove it to the various uses andpurposes for which the gum is applied.

All of the rollers b, d, e and 7 are suitably journaled and arranged tobe actuated by mechanism forming part of the machine, which are notshown or described, as they do not form any essential feature of mydevice, other than in the general modus operandi.

Set in the upper part of the main frame juxtaposition with the peripheryof the distributing roller Z), is a reservoir or trough adapted tocontain the liquid glue or gum, from which it is distributed to theroller 7) as it revolves, either intermittently or corn tinuously,accordingly with the option of the operator, and the class and amount ofthe work passing through the machine.

The reservoir or trough j is formed with a bottom declining towards theroller 1). In normal position the back edge of the bottom engages infrictional contact with the face of the roller 6. The reservoir ortrough is supported in the main frame a of the machine by a link 70, bywhich it is adaptedto be actuated either towards or away from the faceof the roller 6, by a hand wheel Z, for

the purpose of regulating the amount of glue or gum to be fed to theface of the roller, as it revolves.

Set across the back end of the reservoir or trough 7' is a gate atadapted to vertical adjustment to further regulate the amount of glue orgum passing from the main portion of the reservoir under the gate tofeed to the race of the roller, but secondly and especially to preventthe roller from directly contacting and. turning with the main volume ofthe glue, to eliminate all chance of the roller from churning, foamingand overflowing the glue over the sides and ends of the reservoir ortrough, especially as it is found from experience that glue or gum formof spring hinge 0, so that it may be adjusted backwardly as shown indotted lines, when the machine is out of operation, so as not to stickto the face of the roller and to facilitate in cleaning the parts. i

The gate at is held in adjustable relation with the reservoir or troughby a lever rod ,0), pivotally supported to the "front end of thereservoir by a bracket (1 and connected with the grate by a verticallyextending arm r.

a; designates a toot lever pivotally con nected with the main frame, andt is a connecting rod extending between the foot lever and. a crank armuset in the side ofthe t'rame (t, and pivotally connected with a link7), attached with the front end of the lever rod 7 By a downwardpressureon the foot lever s the lever rod 79 is tripped, by which the gate maybe vertically adjusted, to: open a slight interval between the loweredge ofthe gate and the bot'tomof -the reservoir, to allow for asufficient flow of the'glne or gum to pass fronrthe reservoir,

to be taken up by the roller Z) as it revolves, and in turn distributeit equally to the paper or other materials directed through the guiderollers e and 7 from the feed table g.

Thefoot lever may be suitably connected up with the starting andstopping mecha- IiiSDl 'ot the machine, by which all of the operatingparts may be arranged to operate in unison or otherwise, these featuresare apart from the essential features of my device, which lies in thegate or battle, arranged in combination with the reservoir or trough.Various modifications may be made in the shape and means for actuatingthe gate without deviating from the nature oi? my invention.

that I claim as new and desire to secure by Letters PL" '"ent is':

A giiinming machine, in combination with the gum reservoir thereof, saidgum reservoir consisting of a metal trough formed with a decliningbottom, said reservoir located in parallel and juxtaposition with thedistributing roller forming an essential part thereof, an adjustablegate fitted across the back end of the said reservoir, a scraperconnected in hinged relation across the top of said gate, said scraperadapted to engage in tangential'relation against the periphery of thesaid distribi'iting roller, a toot lever arranged in coniunctio-n withthe'said gate and said reservoir, said gate adapted to be verticallyadjusted by the said footdcvcr tor'the purpose of peri'nitting a.determined quantity of glue to escape :t'roni the said reservoir ontothe periphery of the said distributing roller, the said'scraper adaptedto gather amt-direct back into the said reserv'oirthe siiperfl'uousgliiefrom the face of the said roller, substantially as specified.
